A receiving subsystem receives a print job to be raster image processed. The discrete droplets are differentially heated and propelled through etched channels. A phase-locked loop receives the delayed parallel data clock to generate a serial data clock in phase with the delayed parallel data clock. Alternatively, a second capacitor is coupled in parallel to the above capacitor and resistor. The system may further include a fault detector constructed and arranged to detect the fault data in a monitored entity, a fault repository constructed and arranged to store and access the fault object; and a fault handler constructed and arranged to be triggered by the fault diagnosis engine to analyze the fault object.
